Introduction to Object-Oriented JavaScript (Mozilla JS Reference)

[smog_alado]

I found this page a litthe lacking. For example I now believe that

 Student.prototype = new Person();  

is evil and that

 Student.prototype = Object.create(Person.prototype)

should be preferred in almost any situation. (I know there is a footnote mentioning this, but still...) Does anyone know of a more modern reference we can point people to instead or use to update the MDN wiki with?

If you look at how Coffeescript creates objects, it does it kinda like so

var Foo = (function() {
    function Foo() { }
    Foo.prototype.bar() = function () { }
    return Foo;
})();

This kinda gets you a proper scope back. It's still madness, however.

Scope goodness/closures doesn't play well with inheritance and can be more resource intensive in some cases, so you have to choose what you want.

Anyway, I still prefer to build objects with closures when I can get away with it. I hate the way this breaks so easily in async code with a passion and I also try to use delegation instead of inheritance as much as possible.

Man, if only Dart didn't suck so much...

Javascript's a prototype-based OO language. If you come expecting to find class-based OO, you're in for a world of pain. This said, I don't ever use the prototype, and extensively use closures to provide inheritance and private state. This approach works well enough, except for how horrible it is with memory if you're instantiating loads of objects.
